Heat dissipation system for mine car

Abstract

The invention provides a heat dissipation system for a mine car, which comprises a circulating heat dissipation channel, a traction system cooling unit, a water cooling unit for carrying out water cooling on high-temperature cooling liquid and a control protection unit for controlling and protecting the heat dissipation system, and is characterized in that the water cooling unit and the traction system cooling unit are connected in series through the circulating heat dissipation channel; and the control protection unit is arranged between the water cooling unit and the traction system cooling unit. The heat dissipation system has the advantages of high heat dissipation efficiency, small weight and volume of the whole vehicle, convenience in assembly and maintenance and the like.

Description

technical field [0001] The invention relates to the field of heat dissipation for mine vehicles, in particular to a heat dissipation system for mine vehicles. Background technique [0002] With the continuous expansion of large-scale open-pit mines at home and abroad, the role of electric wheel mining vehicles is prominent. At present, large electric wheel mining vehicles undertake the mining and transportation tasks of 40% of coal and 90% of iron ore in the world. In the case of the same output, large-tonnage mining vehicles can reduce the number of vehicles used, improve work efficiency and safety. The power requirements are also increasing, and the heat dissipation system, as an important guarantee for the performance of the traction system, has also increased its requirements. The existing heat dissipation system of mining vehicles usually adopts forced air cooling, which will be difficult to meet the cooling requirements of vehicles in the case of large tonnage and lar...

AI Technical Summary

Problems solved by technology

Since the converter is installed on the walking platform of the whole vehicle, the generator is installed in the middle of the frame, and the wheel motors are installed on both sides of the rear axle, the distance between each component is far, so there are complex air duct design and layout of the whole vehicle, large wind resistance, and fan Problems such as difficulty in design and selection; at the same time, due to the limited installation space of the vehicle, the air cooling system occupies a large space, resulting in difficulty in vehicle design and production assembly

[0004](2) The existing air-cooled heat dissipation method cannot achieve efficient heat dissipation, resulting in the traction system not being able to operate reliably and safely when the mine car is in a large tonnage and large loss

It can be seen that the existing heat dissipation system needs to increase the engine speed in order to provide sufficient cooling air volume, resulting in poor energy saving and fuel consumption.
